Sagot :
Answer:
C
Explanation:
Kinetic Energy formula :
K.E. = 1/2mv²
=============================================================
Given :
⇒ mass = 0.17 kg (needed)
⇒ distance = 20 m (not needed)
⇒ velocity = 22 m/s (needed)
============================================================
Solving :
⇒ K.E. = 1/2 × 0.17 × (22)²
⇒ K.E. = 11 × 0.17 × 22
⇒ K.E. = 1.87 × 22
⇒ K.E. = 41.14 ≈ 41 J
